Merely hours after the 31-year-old announced her split from billionaire shipping heir Stavros Niarchos III, the Australian model was letting her hair down in the Greek Isles with her younger sis and model, Ashley Hart.

In a statement made to the Daily Mail, a rep for the Sydney-born star said Jess was in a good place.

"Yes, I can confirm the split," the statement read. "It was amicable[,] they remain friends and Jessica hasn't been happier!"

And if her 27-year-old sister's Instagram updates are anything to go by, it certainly looks like it!

In a series of holiday snaps from Mykonos, Ashley and Jess can be seen in high spirits, eating their way through the picturesque island and celebrating the birthday of their modelling pal, Kasia Z.
